Caduceus Medical Symbol - History, Meaning, and Usage in Healthcare #98607 (License: Personal Use)

This black-and-white illustration depicts the caduceus, a symbol featuring two intertwined snakes climbing a winged staff, rooted in Greek mythology as the herald’s staff of Hermes. Though often used in medical contexts-especially in the United States-it is technically distinct from the Rod of Asclepius, which has a single serpent and no wings and is the true symbol of healing. The caduceus’ adoption by medical organizations stems largely from historical confusion and 20th-century U.S. military usage.

This image is typically used on educational, medical, or historical web pages explaining symbolism in healthcare; it serves users seeking to understand the difference between the caduceus and the Rod of Asclepius, or researching medical iconography.
